CAN-END-FLANGING AND HEAD-SEAMING APPARATUS.

To all whom it may concern:

Be it known that I, AXEL JOHNSON, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Can-End- Flanging and Head-seaming Apparatus, of which the following is a specification.

The present invention relates to an improved apparatus for flanging the open end of filled cans, crimping a can head to the flanged end thereof, and seaming the criinped head and flanged end to the body of the filled can; the object being to eifeetively carry out the above mentioned steps by the employment of a single intermittently traveling carrier for the filled cans, which carrier successively subjects the filled cans to the action of the fianging means and to the crimping and seaming mechanisms, the carrier receiving and holding the can heads as the filled cans are conveyed from the hanging means toward the crimping and seaming mechanisms.

To comprehend the invention, reference should be had to the accompanying sheets of drawings, wherein- Figure l is a view of the machine in elevation, illustrating the relative arrangement of the various parts, the mechanism for imparting a step rotation to the vertical spindle carrying the conveying means for the filled cans, the drive spindles for the fianging, crimping and seaming rolls, and the mechanism for imparting rotation to said spindles. Fig. 2 is a plan view of the mechanism disclosed by Fig. 1 of the drawings, the guide for the can heads being applied thereto. Fig. 3 is a part sectional detail view (liSClOSiDg the means for actuating the lift plate to place the flanged cans into and out of the sphere of the crimping and seaming mechanism.

illustrated, likewise the guide ring for the upper end portion of the cans, the slides carrying the crimping and seaming rolls, and the hinged knuckles for actuating the same, the seaming roll being moved inward its full distance. Fig. 8 is a detail elevation of the mechanism disclosed by Fig. 7 of the draw ings. Fig. 9 is a bottom plan view of the features contained in Fig. 8 of the drawings. Fig. 10 is a detail view of the rolls for fianging the open end of the filled can, and the vertically movable sleeve carrying said rolls, the same being illustrated in its lowered position, and the Hanging rolls as acting against the open end of a filled can held within one of the semi-circular molds of the upper carrier disk and the swinging mold jaw, the said jaw being removed and carrier disk being broken away and sectioned. Fig. 11 is a detail broken sectional view illustrating the can and can head after having been acted on by the crimping roll to unite the can head to the flanged end of the can. Fig. 12 is a similar View illustrating the can head and can after having been acted on by the seaming r ll of the apparatus.

In the drawings, reference being had to Figs. 1, 2 and 6 thereof, the numeral 1 is used to designate any suitable supporting frame for the actuating mechanism, below the bed of which is extended the cross drive shaft 2. On this drive shaft, which is driven in any well known manner, is secured the pinion 2 which meshes with the pinion 3, secured to the upper end of a short vertical shaft 3, which shaft is supported by a bracket depending from the under face of the frame 1, Fig. l of the drawings. This shaft 3, at its lower end, carries a crank arm 4:, from which depends a rol 4-, which roll during the rotary throw of the crank arm l, wor s successively in and out of the radial slots 5 cut in the periphery of the disk 5, secured to the lower end of the vertical spindle 6, so that from the rotary shaft 3 an intermittent or step rotation is transmitted to the vertical spindle 6. The said spindle 6 extends above the bed of the frame 1, and works within the guide bearing 6. To the projecting portion of the spindle 6, the spaced disks 77 are secured to rotate therewith, the said disks being provided respectively with a series of peripheral can seats 8-8. The disk 7 constitutes the guide disk and the disk 7 the carrier disk of the apparatus.

The filled cans 9 to which the heads are to be applied, are delivered onto the bed of the frame within the sphere of the intermittently traveling carrier 7 and the guide disk 7, by means of the endless conveyor 9, which conveyer works within the can feed runway 10, and is driven from a sprocket wheel 10, secured on the drive shaft 2. The moment a filled can is received within the can seats 8-8 of the spaced disks 7-7, the same is propelled by a step rotation toward the discharge station 11, it being held confined within the can seats of the disks 7-7 after leaving the hereinafter described end flanging mechanism, by means of the curved guard rail 12, which rail is secured to and projects slightly above the bed of the machine. During the travel of the open ended filled can from its receiving point to the discharge station 11, the same is placed beneath the means for flanging the open end thereof and the means for crimping and seaming a can head onto the flanged end thereof, the filled can being held beneath each means sufficiently long to enable the flanging and the crimping and seaming mechanism to successfully perform their respective functions. Preferably, the means for flanging the open end of the filled cans and the means for crimping and seaming the can head onto the flanged end of the filled can, are located at diametrically opposite polnts.

The flanging means comprises the flaring rolls 13-13, which are secured to and carried by the vertically movable sleeve 14. This sleeve is feathered onto the rotatable spindle 14, which spindle rotates within the guide bearing 15, depending from the overhanging portion 15 of the bracket 16, upwardly projecting from the bed of the machine. To the upper end of the spindle 14 is secured a pinion 16, which meshes with the pinion 17, secured to one end of the short horizontally disposed shaft 17, working in bearings of the brackets 18-18 carried by the overhanging portion 15 of the bracket 16. The shaft 17 has secured to its opposite end a pinion 18 for actuating the hereinafter described seaming mechanism, and the said shaft is driven by any suitable means, preferably by means of a drive belt, not shown, working over the drive pulley 19.

The sleeve 14 is raised and lowered on the rotating spindle 14, by means of the hinged arm 19, the free or outer enlarged forked end of which rests within the grooved portion 20 of the sleeve 14, the inner end of the hinged arm being hinged to the lift rod 20. This rod extends through a guide opening in the bed of the machine, and the lower forked end 21 thereof straddles the drive shaft 2 to guide the rod and from such end projects a roll which works within an eccentric groove cut in one face of the cam 21,

secured to drive shaft 2.

In order to hold the filled can during the operation of the flanging rolls 13-13, there is provided a half jaw mold 22, which, when swung inwardly, registers with one of the peripheral seats 8 of the carrier disk 7, so as to entirely encircle the can end to be flared or flanged. The jaw section 22 is a swinging one, the same being secured to the lower end of the rod 22, which rod is connected to the rock-shaft 23, working in the guide bearing 23, projecting from the guide bearing 15 for the spindle 14. The said rock-shaft 23, has secured to one end thereof the crank-arm 24, which arm is connected to the upper end of the actuating rod 24. This rod extends through a guide opening in the bed of the machine, and to the lower end thereof is held the projecting roll 25, which works within an eccentric groove cut in the face of the cam 25, carried by the drive-shaft 2.

The crimping or seaming mechanism consists of a plurality of independently laterally movable rolls 26-26, loosely mounted respectively on the studs 27-27, depending from the slide plates 28-28, movable in the guide-ways 29-29, secured to the head 30 of the rotatable tubular spindle 30; Figs. 1, 7 and 8 of the drawings. This spindle works through the guide 30 secured to the overhang 15 of the bracket 16, and is driven from the pinion 18 by means of the pinion 29 secured thereon meshing with the said pinion 18 On the tubular spindle 30 is feathered the vertically movable sleeve 31, which sleeve carries the inclines 3232, for operating respectively the hinged knuckles 3333, the tail extensions of which knuckles engage respectively with the slideplates 28-28 to move the same within the guide-ways 29-29. The crimping or seaming rolls work within the cut away portions 34-34 of the guide ring 35, which is bolted to the lower end of and depends from the spindle head 30, the lower edge portion of the inner face 35 of which ring is beveled or outwardly flared so as to properly position the can head loosely applied to the filled can, as the same enters the guide ring while being forced against the clamp disk 36 held at the lower end of the spindle 30 by the stem 36 of the disk 36, which extends through the spindle 30 and is held against rotation in the overhang 19 of the bracket 18. This disk 36 acts against the can head resting on the filled can, and holds the same in place during the operation of crimping and seaming the same to the flanged end of the held can.

The filled can, with its loosely applied head, is forced upwardly to place its open end into the guide ring and force the head thereof against the clamp disk 36, b means of the vertically movable lift plate 36 which plate works within the seat 37 in the bed of the frame, Figs. 1, 3 and 5 of the drawings. The tubular stem 37 of the plate 36 extends below the bed of the machine and is held within the depending guide sleeve 38 against rotation by means of the cross-pin 38, which extends through the vertical slotted portion of the stem 37 and through the guide sleeve 38.

The projecting ends of the cross-pin 38 rest within seats formed in the forked end of the fulcruined lever l0, which carries a roll it) that works within an eccentric groove cut in one face of the cam ll, secured on the drive-shaft 2. This cam as rotated by the drive-shaft 2, acts against the roll to to actuate the fulcruined lever l0 to raise and lower the guide sleeve 88 carrying the lift plate 36 the sleeve and the lift plate being held against rotation, during the action of the crii'nping and seaming rolls on the held can, by reason of the securing cross-pin 3S resting in seats cut in the face of the forked end of the fulcrumed lever it). As the plate is raised, the filled can 2) is forced upwardly within the guide ring and the loosely applied head 9 of the can is firmly pressed against the clamp disk 36, so that the can will be held between the left plate and the said disk 36, and the loosely applied can head 9 securely held in position.

The vertically movable sleeve 31 is raised and lowered on the spindle 30 to cause the inclines to act respectively against the knuckles 3333 to operate the slides 2828, by means of the fulcrumed lever 42, the forked end 42 of which rests within the circumferential groove 42 of the sleeve 31. To the inner end of the lever 2L2 is connected the actuating rod 43, which works through a guide opening in the bed of the machine frame, the lower forked end 43 of the said rod straddling the drive shaft 2 to guide the same, and a roll secured to such forked end of the actuating rod 43 working within an eccentric groove cut in one face of the cam 44 on the drive-shaft 2. The spindle 30 is driven from the upper shaft 17 by means of the pinion 18 which pinion meshes with the pinion 29 secured to the upper end of the spindle The carrier disk 7 is somewhat thicker than the guide disk 7, and the peripheral seats 8 of the said disk 7 may be said to constitute semi-circular fixed molds for the cans 9 received therein, and hereinafter the said seats shall be expressed as fixed semicircular molds, which are completed by the registry therewith of the swinging semi-circular jaw 22, when the same is thrown inwardly to encircle or clamp the upper portion of the filled can and hold the same during the action of the flanging or flaring rolls 13l3. The upper inner surface of the semi-circular fixed molds 8 of the carrier disk '7 is chamfered to provide a seat 8 for the receiving of the can head 9 delivered thereto just prior to the filled can 9 being placed onto the lifting plate 36 which head is delivered onto the seat 8 through the curved guide plate M into which the heads are fed in any suitable manner. This guide plate as for the can heads and the position which the same may assume relative to the carrier disk 7, will be understood by reference to Fig. 2 of the drawings. To provide against slippage of the filled can 9 while being acted on by the rapidly revolving crimping and seaming mechanism, the upper surface of the lift plate 86 is roughened to form a series of radial projections L5, Figs. 4: and 5 of the drawings.

The following is a brief outline as to the operation of the various parts during the flanging of the open end of a filled can, and the crimping and seaming of a head to the flanged end of the can The filled cans 9 are placed within the feed runway 10 and are successively delivered by the endless traveling conveyer E) onto the bed of the frame 1 within the sphere of the intermittently rotating carrier and guide disks and are propelled by said carrier disks beneath the flanging rolls l3-l3, the upper end portion of the filled can resting within one of the semi-circular ilXQtl molds 8. By this time the eccentric will have acted to draw downwardly the actuating rod 2%, to operate the rock-shaft 23 so as to throw inwardly the rod 22 and cause the jaw or mold section 22 to register with the mold section 8 of the carrier disk 7 to clamp the filled can therein. The am 21, when the can 5) stands thus positioned, then acts to raise the lift rod 20, causing the same to gradually depress the outer portion of the hinget arm 19, so to move down wardly the sleeve 1-l carrying the flanging rolls l3 13, which are rotated at a high speed by the rotating spindle ll. These rolls gradually bear onto the open end of the filled can 9, and during the descending movement thereof, due to the inclination thereof, gradually outwardly turn or flare the end of the filled can 9 to form the flange 9 Fig. 10 of the drawings. The carrier disks remain stationary (hiring the action of the Hanging means, but the moment the end of the can has been properly flanged, the eccentric 25 and the cam 21 continuing their rotary iovement, act to release the clamp jaw or mold section and to operate the lift rod 20 to raise the sleeve 14 and its flanging rolls 13l3 from the can 9. The crank 4 then acting within the radially slotted disk 5 advances the flanged filled can 9 by an intermittent movement over the surface of the bed of the machine, until the same is positioned on the lift plate 36 with the can head 9 resting in the seat 8 of the fixed semi-circular mold 8 of the carrier disk 7, within which is held the flanged filled can, so that the head 9 to be applied will he immediately above the open flanged end of the can. The cam 41 then acts onto the fulcrumed lever 40 to raise or lift the plate 36 to force the open flanged end of the can 9, into the guide ring 35, carrying the loosely held head 9 against the clamp disk 36. By this time the cam 44 will have advanced to raise the actuating rod 43, throwing the fulcrumed lever 42 to cause the sleeve 31 to gradually move downwardly on the head 30 of the rapidly revolving spindle 30, causing the incline 32 to act against the hinged knuckle 33 to force the slide 28 inwardly, causing the roll 26 to bear against the downwardly extended portion of the flange of the can head 9 with an increasing pressure and to gradually crimp the same onto the outwardly flared or flanged end of the filled can, Fig. 11 of the drawings. The shape of the crimping roll 26 is such as to turn the downwardly extended portion of the can head flange over onto the flanged end of the can 9. The continued rotation of the cam 44 reverses the movement of the actuating rod 43, throwing the fulcrumed lever 42 to raise the sleeve 31, causing the lower incline 32 to act against the hinged knuckle 33 and force the slide 28 inwardly, the slide 28 gradually moving outwardly due to the overweight of the upper end of the hinged knuckle 33, which normally holds the upper end of the same inwardly against the sleeve 31. As the slide 28 is forced inwardly, the periphery of the seaming roll 26 bears against the crimped flange of the can head 9 and gradually closes the same and the circular end flange 9 of the filled can firmly against the body of the can 9, Fig. 12 of the drawings. After the can head has been seamed onto the filled can 9, the cam 44 acts to lower the sleeve 31 to place the incline 32 out of engagement with the hinged knuckle 33, when the over-weight of the upper end thereof throws the same inwardly toward the sleeve 31, moving the slide 28 and the seaming roll 26' carried thereby outwardly or away from the seamed can. The fulcrumed lever 40 is then acted on through its connection with the cam 41 to lower the lift plate 36 to take the headed can from within the guide ring The released can is then advanced by the rotatable carrier disks toward the discharge station or section 11 of the machine, at which point it is discharged from within the carrier disks; being ejected by bearing against the outwardly curved or inclined ejecting rail 42 which projects from the bed of the machine within the path of propelled cans and serves to gradually remove the same from the carrier disks. It ofttimes happens that the can bodies vary slightly in length, and to compensate for such variations it is required that a slight give be permitted the lift plate 36 To successively accomplish this, a spring 45 is located within hollow stem 37, which spring is interposed between the under face of the lift plate 36 and the crosspin 38, the tension of such spring being regulated by the adjusting screw 46.
